Has anyone had a problem with the spark plugs rusting on their A4. I have a Catalina 27 with an A4, and recently had a spark plug fly apart. It appears that the spark plug rusted through until it was too weak to hold the pressure of the cylinder.
I would like to know if this is a common problem, and if so what can be done to solve it.
